tpm: Use container_of to locate the tpm_chip in tpm_open
misc_open sets the file->private_date to the misc_dev when calling open. We can use container_of to go from the misc_dev back to the tpm_chip. Future clean ups will move tpm_open into a new file and this change means we do not have to export the tpm_chip list. Signed-off-by:Jason Gunthorpe <jgunthorpe@obsidianresearch.com> Reviewed-by:
